What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRadiodermatitis (RD) is an inflammatory lesion of skin mucosa caused by radiation, which causes itching and pain in patients' skin. Hypericum sampsonii has an anti-inflammatory effect. This study aims to explore the potential effect and mechanism of H. sampsonii on RD. MATERIALS AND
methodsThe RD model was established using X-ray irradiation of mice and the pain response of mice under different treatment methods. Serum levels of IL-1β, IL-6, and TNF-α were measured by ELSA. The RD cell model was constructed by RAW264.7 cell, H. sampsonii intervention was conducted, and the changes of the NLRP3 inflammasome in the cells were detected by qRT-PCR. The cells were stimulated with LPS and the protein changes of TLR4/NF-κB were investigated by Western Blotting.
resultsH. sampsonii can better improve the skin status of RD mice, relieve pain, and reduce the secretion of serum inflammatory factors IL-1β, IL-6, and TNF-α. H. sampsonii significantly down-regulated the expression of NLRP3, Caspase-1, pro IL-1β, and IL-1β. Lps-induced activation of the TLR4/NF-κB pathway promotes the expression of NLRP3 and pro-IL-1β, and H. sampsonii can inhibit this promotion.
conclusionH. sampsonii may inhibit NLRP3 inflammatory vesicle activation via interfering with TLR4/NF-κB signaling to reduce the inflammatory response in macrophages and thus play a role in the treatment of RD.
